abstract
Flow control Structures that remain in place for more than one irrigation season are considered permanent. The control structures moved from one place to another place during every irrigation are installed for one season as considered as temporary. Temporary structures are required on most irrigated farms, but permanent structures normally permit better water control with less labour. The cost of temporary and permanent irrigation control structures can often be reduced by combining two or more structures wherever possible. These are like checks, drops, divisors, turnouts or combined with various combinations. In this to develop control unit FRP, HDPE, PVC, PP, MS, GI was used, different costs to develop modules are base material cost, preparation cost, welding labour cost, filler material cost, Gases cost was considered from this observed that cost of development of modules with PP is less.
